To make your vehicle more visible to other drivers during daytime driving, the
daytime running lights turn on automatically whenever the engine is started
and the parking brake is released with the headlight switch off or in the
“AUTO” position. (Illuminate brighter than the front position lights.) Daytime
running lights are not designed for use at night.
■ Headlight control sensor
■ Automatic light off system (if equipped)
Vehicles without a smart entry & start system
● When the light switch is in or : The headlights and front fog
lights turn off automatically when the engine switch is turned to the “LOCK”

detecting the level of ambient light and
may cause the automatic headlight sys-

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound, the PCS activation indi-
cator will flash*1 or a warning
message will be displayed in
the multi-information display*2,
and the system will urge the
driver to take evasive action.
*1: Vehicles with monochrome display.
*2: Vehicles with color display.
: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle is high, a
warning operates to urge the driver to take evasive action and
the potential brake pressure is increased to help the driver avoid
the collision. If the system determines that the possibility of a
frontal collision with a vehicle is extremely high, the brakes are
automatically applied to help avoid the collision or help reduce
the impact of the collision.
The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. ( P. 297)

• If the wheels are misaligned
• If a wiper blade is blocking the front sensor • The vehicle is wobbling.• The vehicle is being driven at extremely high speeds.
• When driving on roads with sharp bends or uneven surfaces • When a preceding vehicle is a poor reflector of laser
● In some situations such as the following, sufficient braking force may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when the brake parts are extremely cold, extremely hot, or wet• If the vehicle is not properly maintained (brakes or tires are excessively worn,
improper tire inflation pressure, etc.) • When the vehicle is being driven on a gravel road or other slippery surface
• If your vehicle is skidding
• When the front part of the vehicle is
raised or lowered
